migrating minor rails versions

问题:

I started a new rails project a few weeks ago with 3.2.3. Today I noticed that rails 3.2.4 and 3.2.5 have been released. I don't want to be behind already, so what's the best way to update my app to 3.2.5?

回答1:

• Read the release notes.
• Edit your Gemfile and run bundle update.
• Update your .rvmrc file. (Optional)
• Run your tests.
• Repeat as necessary.

One caveat is that if you do not explicitly specify gem versions in your Gemfile you may update a gem and introduce breaking changes; I have been bitten by this because of my Gemfile laziness.
